 Summary: Spurious warning CS0169
 The warning CS0169 "Private field `A.name' is never used" is reported
 e.g.  Try to compile with -warn:4
@@ -50,6 +49,25 @@
 Don't we emit warning messages like "varibale X assigned but never
 used" for a local method? Wouldn't this just be an extension of that?
 OTOH, in the local variable case, the jit is free to optimize away the
 variable -- it isn't really keeping anything alive. This isn't true in
 the case of a field.

+I think we can close this as we simply report more warnings than csc.
+And because csc does report warning for code like this, it is simply
+csc bug (not first one in their warning code).
+public class A {
+    public A(string name)
+    {
+       	string name2;
+	name2 = name;
+     }
+    static void Main () {}
+Note: csc reports no warning for this but when you compile with /o+ no
+code is emitted for ctor.
